Hello, has anyone tried the updated version of Schroth - the "Schroth Best Practice" approach? It's a simplified, milder, and shorter version of the Schroth for those with less than 70*, I believe. I'm trying to decide if the Schroth Best Practice would be more suitable for my 13 yr old daughter (who has 15* TL) over the traditional Schroth. Any input? Thank you.
